JBUFFING 0R POLISHING WHEEL.

answer.

To all whom it may concern.-

Be it known that l[, Gnoncn 1P. KELLER, a citizen of the United'states, and a resident of Hoboken, in the county of Hudson and State of New Jersey, have invented a new and Improved Bufling or Polishing Wheel, of which the following is a full,-

clear, and exact description.

The invention relates to buffing or polishing wheels formed of a plurality of folded pieces of muslin or other fabric material.

The ob ect of the'invention is toprovide a new and improved buffing or polishing wheel arranged to prevent the peripheral partly overlying third folds, the doubled-up.

side of one folded fabric piece extending between the second folds of the next following fabricpiece, the scalloped edges of each piece overlying one the other and the scalloped edges of the several pieces forming the peripheral face of the wheel.

A practical embodiment of the invention is represented in the accompanying drawings forming a part of this specification, inwhich similar characters of reference indicate corresponding parts in all the fviews.

F igurel is a'plan View (if the fabric material from which the wheel pieces are cut; Fig. 2 is an enlarged plan view of one of the pieces prior to folding; Fig. 3 is'asimilarview 'of the same after being doubled up lengthwise to form the primary folds; Fig. 4 is a similar view of the same after being doubled up transversely; Fig. 5 is a similar view of the completely folded piece; Fig. 6

is a face view of one side of the wheel with the pieces assembled; Fig. 7 is a similar View of the other side of the wheel; Fig. 3 is a face 'view' of one of the outer fabric disks, Fig.9 is a face I .of the wheel with the covering disk par broken out to show the center disk and the folded pieces;- Fig. 10

\ is aplan view Ora fabric wheel piece of modified form; and Fig. 11 is ajfface view of Specification of Letters Patent.

cut at bias from a piece of fabric material B, as shown in Fig. 1, and each piece is in the form of an elongated endless band .hav-' ing a scalloped edge. The end scallops A and A are semicircular and the intermedi; ate scallops A A and A A are each in the form of a quarter circle. The opening A of the endless band is produced by cut-' tingout two circular pieces eccentric relatively'to the end scallops A and A as plainly shown in Fig. 2. The outer .walls of the openings intersect the centers of the scalloped ends A, A ,'and the inner edges of the cut-out portions are arranged tangentially relatively one to .the other, the triangular portions adj acent the tangential inner ends being also cut out to produce the opening A as shownin Fig. 2. The piece A. of the shape described is first doubled up along its longitudinal center line indicated in Fig.

2, to provide a primary fold, shown in Fig.

3, with the corresponding scalloped edges in register with each other. The doubled-up piece is now doubled up transversely, as

shown in Fig. 4, to form overlying second folds, which in turn are doubled up to form partly overlying third folds, as indicated in Fig.5. the arrangement described the several scallops each in the form of a quarter circle are in register with each other and form the peripheral face-of the piece, and eight suchfolded pieces are arranged in a circle to form the buffing or polishing wheel.

By' reference to Fig. 11 it will be noticed that the individual folded pieces are-assembled in such a manner that the doubledupside of one folded fabric piece extends between the second folds of the nextv following folded fabriopiece, the registering scalloped edges ofthe several pieces forming the peripheral face of thewheel. By, ar-' ranging the individual eight ieces in the manner described, the outer ege of one of the third folds of each piece extends approximately radially, as plainly indicated in Fig. 6, while the outer edge'of the other third fold extends at an obtuse angle from.

the peripheral face of-the wheel, as'indi-* cated in Fi 7. By the arrangement described the-individual pieces are symmetrically-arranged and interlocked with the peripheral edges of the pieces presenting a bias out peripheral surface, so that the material is not liable to unravel while being the end clamping plates in the usual manner so that further description of the same is not deemed necessary.

If desired,,more.than A or A A may Fig. 10, in which two more clamps A are interposed between the edges A A and In this case two more circular pieces are cut out of theblank to form the elongated opening A". Fig. 10 is first doubled up lengthwise, then doubled up in' a transverse direction the same as above described in reference to Figs. 2 3 and 4, and then is doubled up again in a transverse direction and finally once more-in a similar direction until all the scalloped edges are in register one with the other, and the folded pieces are assembled in a-circle in the same manner as above described so that further description of the two scallops A same is not deemed necessary.

Having thus described my invention, I claim as new and ters Patent:

1.- A bufling or polishing wheel, compris- Any number of such.-

be used as indicated in' The piece shown in desire to secure by Leting a plurality of folded fabric pieces, each piece being bias cut and in the form of an elongated endless band having a scalloped edge, the band being doubled up lengthwise to form a primary fold, which is doubled up transversely to form overlying second folds, which are doubled up to form partly overlying third folds, the doubled-u side of one folded fabric piece extending between the second folds of the next following fabric piece, the scalloped edges of each piece overlying one the other and the scalloped edges of the several pieces forming the peripheral face of the wheel.

2. A bufling or polishing wheel, comprising a plurality of folded fabric pieces, each piece being bias out and in the form of an elongated endless band having a scalloped edge,the band being doubled up lengthwise to form a primary fold, which is doubled up transversely. to form overlying second folds, which are doubled up to form partly overlying third folds, the doubled-up side of one folded fabric piece extending between the second folds of. the next following fabric piece, the scalloped edges of each piece overlying one the other and the scalloped edges of the several pieces forming the peripheral edge of the wheel, the outer edge of one of the third folds of each piece extending approximately radially. V

In testimony whereof I have signed my name to this specification 1n the presence of two subscribing witnesses.
